The CR3002AB is a kind of transient voltage suppressor (TVS) diode. This device is designed to prevent any form of high-voltage surge or spike on an electronic circuit. It acts as a safeguard and safeguards the circuit and the connected components from further damage. The TVS diode works by providing an instant clamping action to limit the excess voltage and current. It is also able to operate with high dissipation as well as low-power consumption.
CR3002AB is a low-flow current and high-voltage dissipation device, featuring an ultra-low on-state resistance (RDS (on)) of 0.015Ω. It can take excess current up to a maximum of 10A and limit it to 40-70V. It is designed for bipolar, unidirectional, and full-wave applications. The device is constructed using two anti-parallel silicon chips with anode on one side and cathode on the other. The anode and cathode connections are made using terminal pins. The reverse breakdown voltage (VBR) available for this device is between 25 and 40 V. It has been rated at 8 kV as per the IEC61000-4-2 ESD immunity requirements.
The working principle of the CR3002AB is based on the avalanche effect. When an external voltage source is applied with reverse polarity, the TVS generates a depleted region beneath the junction which cause the sudden multiplication of the electrons that pass through the junction. The subsequent effect is breaking of the junction say in an anode-cathode direction, which eventually causes an avalanche breakdown of junction. This breakdown mechanism is accompanied by rapid and high heat production. The device is designed to limit or regulate this excess voltage and discharge the excess heat.
The major application of CR3002AB includes suppressing the line-to-line and system level transients, and pre-loading in power MOSFETs. The device is employed in portable applications such as cellular phones and PDAs in the form of overvoltage and overcurrent protection for system level and I/O ports. It is also used as a control signal and low speed isolator in automotive applications. The popular areas of the application of this device include consumer electronics, electric/electronic power supplies, telecommunications, automotive, and cutting-edge high-speed logic protection.
